' f7- 4. v Zsmsentor 8g 1 2 v I attorney.

Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE 1 Claim.

The particular object of my invention is to provide advantageous means in connection with bank-tellers counters or the like, for conveniently insuring accuracy in the counting and inspection of paper currency; and to this end it consists in a bill-illuminating counter attachment as fully set forth in connection with the accompanying drawing illustrating a preferred embodiment thereof, the novel features being specifically defined in the subjoined claim.

Fig. 1 is a perspective view indicating the preferred application of the invention as a removably-secured attachment to a bank-tellers counter.

Fig. 2 is a plan view of the attachment as indicated in Fig. 1; Fig. 3 is a cross-sectional view on the line 33 of Fig. 1; and Fig. 4 is a plan view of the casing, similar to Fig. 1, but with the top closure removed to fully reveal the construction and the arrangement of the bill-illuminating means.

The bill-counting table A is indicated as an ordinary bank-tellers counter, to which my invention is applied as an independently formed attachment; this being a preferred arrangement particularly because it involves no change in the ordinary counter, but mere application thereto of the separately complete attachment B.

The preferred means indicated for securing my attachment to the counter consists merely of a bracket C comprising a plate fixable to the counter and provided with apertures c c in which supporting means D secured to the attachment are engagea'ble to removably hold the attachment to the table with their top surfaces approximately level.

The attachment B, as shown, comprises a rectangular electric-light casing 29, which is formed with a main bulb-chamber 5 and an adjoining socket-connection chamber H). The intervening partition I5 serves in connection with a clip I I, to support the socket 12 in chamber lfl,to which socket the bulb 6 in chamber 5 is secured; circuit wires [3, [4 extending through the end wall 2| of the casing.

The walls and floor of the bulb-chamber 5 are provided with light-reflecting inner surfaces so 5 as to concentrate the light for deflection through a window 3| provided in the cover-top 3! of the casing. This window, as indicated, is located out-of-centre relative to the electric bulb 6, so that the light from the latter will be. discharged 10 angularly as determined by the convenient positioning of the bills in counting of them by the teller; and it may be provided with plain, frosted, or magnifying glass, as preferred,ventilating openings 1 being provided in the walls of the 15 chamber. The top cover 36 is conveniently formed separately, and removably secured to the main casing, as indicated, so as to enable free access to the illuminating means, and the whole attachment may be readily removed or ad- 20 justed as convenience requires; the preferred construction and arrangement specifically de scribed however being capable of modification within the invention as defined in the claim.

What I claim is: 25

A bill-illuminating counter attachment consisting of an electric light casing securable to said counter with its top surface substantially at a level with the latter and having a bulbenclosing chamber with light-reflecting walls, an 30 adjoining socket chamber, and a partition wall separating said chambers, a lamp socket in said socket chamber having circuit connections extending through an outer chamber wall and its open socket end extending through said par- 35 tition wall, a light bulb in said light casing engaging in said open socket end, and a light-transmitting window in the top closure of said bulbenclosing chamber disposed laterally with respect to the light bulb enclosed in said chamber. 0
